4.The mechanics of the player itself however can be quite sturdy, and are generally not as prone to permanent damage due to being dropped as hard drive-based players. 译文：这种播放器比硬盘型播放器坚固，一般不容易因摔到地上而出现永久性损坏。 as … as: 指“两个人或物在某方面一样”，既可以用在肯定句里，也可以用在否定句中，而so ... as ...只能用 在否定句里。 prone to: 很可能，如：People are more prone to make mistakes when they are tired.
Digital audio players are generally categorized by storage media: Flash-based players: These are non-mechanical solid state devices that hold digital audio files on internal flash memory . Because they are solid state and do not have moving parts, they require less battery power, and may be more resilient to hazards such as dropping or fragmentation than hard disk-based players. Hard drive-based players or digital jukeboxes: Devices that read digital audio files from a hard disk drive (HDD). These players have higher capacities as of 2010 ranging up to 500 GB. At typical encoding rates, this means that tens of thousands of songs can be stored on one player. The disadvantages with these units is that a hard drive consumes more
USB host/memory card audio players: Players that rely on USB flash drives or other memory cards to read data. PMPs are capable of playing digital audio, images, and video. Usually, a colorliquid crystal display (LCD) or organic light-emitting diode (OLED) screen is used as a display. Various players include the ability to record video, usually with the aid of optional accessories or
stored on CDs. Such players are typically much less expensive than either the hard drive or flash-based players. The blank CD-R media they use is very inexpensive, typically costing less than US$0.15 per disc. These devices have the feature of being able to play standard "Red book" CD-DA audio CDs. A disadvantage is that due to the low rotational disk speed of these devices, they are even more susceptible to skipping or other misreads of the file if they are subjected to uneven acceleration (shaking) during playback. The mechanics of the player itself "however" can be quite sturdy, and are generally not as prone to permanent damage due to being dropped as hard drive-based players. Since a CD can typically hold only around 700 megabytes of data, a large library will require multiple disks to contain. However, some higher-end units are also capable of reading and playing back files stored on larger

Networked audio players: Players that connect via (WiFi) network to receive and play audio. These types of units typically do not have any local storage of their own and must rely on a server, typically a personal computer also on the same network, to provide the audio files for playback.
